Charlie Sheen gets a father figure on his show — Martin Sheen

Charlie Sheen was a swirl of outrageous behavior during the public meltdown that led to his ouster from CBS' "Two and a Half Men." But in his appearance at FX's Television Critics' Assn. panel on Saturday, Sheen was more mild than wild. The most outrageous thing about him was his wardrobe.

In what may have been a TCA press tour first, Sheen wore plaid shorts and no socks as he sat alongside his costars of "Anger Management" and the show's executive producer, Bruce Helford. And instead of brash and outlandish outbursts, Sheen seemed subdued and almost a bit shy and uncomfortable.

"I don't know — I learned a lot," he said as he tried to deflect a question about how his life was different now as opposed to his more infamous phase. "Stick to what you know. Don't go on the road to 21 cities with no act."

Sheen was more at ease when discussing "Anger Management" and the likely addition of his father, Martin Sheen, to the cast if the series is renewed. Martin Sheen guest stars as the father of Charlie Sheen's therapist character in the ninth episode of the series.

"He was great, he was awesome," Charlie Sheen said when discussing about working with his father, who had also appeared with him on "Two and a Half Men," "Spin City" and in the movie "Wall Street." "He brings a whole different energy."

A clip from the episode showed the Sheens bantering in a bar, with the elder Sheen launching into a few drunken celebrity impressions. One impression was of Marlon Brando, Martin Sheen's costar in "Apocalypse Now," delivering the infamous "delivery boy" line that Brando says to Sheen in that film.

Charlie Sheen added that he was "excited as hell" about the series. And unlike previous interviews, there was barely any mention of his former series or Chuck Lorre, the producer of that show that Sheen viciously attacked in several interviews.

Helford said that, unlike on "Two and a Half Men," Sheen has an active creative voice in the series: "We're building this together."

FX President John Landgraf said he was pleased with the ratings of "Anger Management," and that they had exceeded the audience needed for the network to order an additional 90 episodes under a deal with the show's producers and distribution arm, Debmar-Mercury.

Athough a final decision won't be made until after the first 10 installments air, he said the series would most likely be renewed. Adding Sheen Martin adds another dimension to the show, a "multigenerational family" element similar to "Two and a Half Men."
